List,
There is a short article about DBMS_RANDOM in the Sept/Oct issue of ORACLE magazine. It is a quick explaination on the usage and a method to get the text usage. www.oracle.com/oramag/ for the article.
Basically as SQL> select text from all_source where name = "DBMS_RANDOM" and type = "PACKAGE" order by line;

Jack, Chris,

Thanks. Don't get play with these a whole lot being on the production side. Both of your experiences with this sounds very exciting.

Need to do some research.

Thanks again.
